On Cloudrunner 2

Who Are On Cloudrunner 2 For?

The Cloudrunner 2 is built for beginner-to-intermediate runners who want a dependable, supportive daily trainer for easy and moderate mileage. It suits those who value stability and comfort over speed — runners logging steady base miles, not tempo hounds chasing personal bests. If you want a lightweight racer or a springy carbon rocket, look elsewhere in the lineup.

Feelings and Experience

Underfoot the Helion foam feels comfortable and controlled rather than plush or bouncy — supportive and even-keeled, with a smooth, planted transition. The wide base keeps you steady when you slow down or fatigue sets in, though the flip side is that it stays composed rather than energetic when you push the pace, feeling a touch flat if you ask for a real turn of speed.

Performance Specs

• Drop: moderate heel-to-toe offset — a balanced ride that neither forces the forefoot nor sinks into the heel

• Cushioning: above-moderate, Helion EVA-blend foam — durable comfort for daily miles

• Responsiveness: medium — a composite Speedboard adds structure and smoothness, but this is not a springy superfoam

• Stability: high, stable-neutral — a wide platform and firm sidewalls guide without a dedicated medial post

• Pace: Optimal for 5:30–6:30 min/km (8:51–10:27 min/mile) — its comfortable steady zone

Best Distances and Maximum Speed

The Cloudrunner 2 is at its best over 10K and the half marathon, with the half as its true sweet spot for steady, controlled efforts and long training runs. It has a little more in the tank when needed: its fastest effective zone sits around 5:00–5:30 min/km (8:03–8:51 min/mile), where the Speedboard keeps transitions crisp before the foam runs out of pop.

Technologies and Materials

The midsole uses On's Helion EVA-blend foam paired with CloudTec cushioning pods and an internal composite Speedboard (a plastic-based plate, not carbon) for structure. An engineered mesh upper and a rubber outsole round out a build tuned for durability over raw speed. Weight and stack height aren't specified here, but the overall feel is that of a solidly cushioned, ground-hugging daily trainer.
